On the freezing of assets of mob boss Dawood Ibrahim by the UK, Singh said: "We do not want to let the cat out of the bag."

Asked if India was hopeful of bringing back former Naval officer Kulbhushan Jadhav, sentenced to death by a Pakistani military court on the charge of espionage, he said some matters were being handled "very delicately and there is no point in putting out anything till things solidify".

India had on May 8 taken the Jadhav case to the International Court of Justice, accusing Pakistan of violating the Vienna Convention and conducting a "farcical trial".
